Park Tool's Power Lift Shop Stand is the biggest, strongest, stiffest, most versatile repair stand ever built. Park created the PRS-33 with professional mechanics in mind, blending a massive upright with the ease and convenience of a powered lift. The size and strength ensures a super rigid workstation able to go higher than ever before and the power lift allows effortless height adjustment for any bike up to 120 pounds (54kg). It's perfect for lifting heavy electric bikes or for mechanics with lifting limitations, but also great for easy height changes during a repair or set up. The PRS-33 is a single arm stand but can be made into a double arm stand with the addition of part number PRS-33 AOK (sold separately).
• Adjustable height from 6” to 78” (16cm-198cm)
• Integrated work tray
• Integrated accessory bar to hang wheels, air hoses, lights and just about any other accessory you can think of
• Electric motor able to smoothly lift 120 pounds (54kg)
• Oversized gussets to mount stand directly to the floor or to part #135.33 115 pound (52kg) Base Plate (sold separately)
• 100-3D Micro Adjust clamp
• Full height with base and accessory bar: 94" (239 cm)
• Not using the accessory bar will reduce the height by 2-3/4"

Shimano's R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction. The R9100 cranks set the highest standards for stiffness and lightness. With the first integrated power meter, you can expect extremely accurate data. The FC-R9100-P is Shimano’s first power meter, as well as Shimano’s first crank-integrated power meter on the market. It retains its unique asymmetrical four-arm spider construction, but with a ‘brain’ mounted on the inside. On its crank arm are the strain gauges. Working perfectly in sync with each other, you can use the extremely precise power data to improve your performance.

- Compatible with 3rd party displays
- Bluetooth / ANT technology
- Hollowtech II construction
- Hollowglide chain
- 11-speed compatible
- Waterproof in all conditions
- ±2% accuracy of strain gage measured power
- Integrated rechargeable battery
- Simple zero reset with switch on transmitter
- Average weight (170mm, w/o BB): 691 grams (53-39T)/679 grams (50-34T)

Driven to perfection
Perfection has finally become a reality.
The Drivo hometrainer measures power output with extreme accuracy.
The Drivo's precision is unprecedented making it unique among hometrainers.
ACCURATE MEASUREMENT
Your workout will never be the same, Drivo is the interactive trainer that measures the power of each ride on 24 points and with an accuracy of +/- 1% . The power meter integrated in fact allows to determine the watts with the same precision of scientific measuring instruments. Basically, you have all the advantages of a professional tool , but the convenience of a system easy and intuitive .
ROUNDNESS RIDING
Even if you're training indoors, you'll hear the same roundness of pedaling when you're outdoors . The internal flywheel 6 kg has been dimensioned to make you relive the same feeling as when under the wheels there is the road . In short, the training is indoors, the emotions are instead of when you're outdoors.
SILENT
When you train you do not want to be bothered by anything or anyone. Drivo is so silent that while the pedals do not feel anything at all , apart from the noise of the chain and effort fatigue. So you can stay focused as you prepare to always move a little 'beyond your limits to achieve new successes .
INTERACTIVE AND COMPATIBLE
You choose the path or training program, Drivo automatically varies the resistance and is compatible with the best apps and programs . In fact, the management of the trainer can take place with the Elite programs or platforms with third parties . You can also connect Drivo in computers, smartphones and tablets : to manage the training parameters anywhere, and at any time.
PEDALING ANALYSIS
The Analysis of pedaling is the new developed by ELITE exclusive function for the roller holders DRIVO with which is analyzed
the power developed by the cyclist pedaling in the entire arch.
With this function the cyclist can see the change in the power supplied during the entire pedaling, pedaling coordination as a result of the combined work of the extensor muscles and those flexors and then ultimately the pedaling smoothness and efficiency mechanics of athletic movement.
